Observation 45051: Lentaria Corner
When: 2010-04-24
No herbarium specimen

Notes: This very fine fungi was about 3-5mm in height. It was only growing on one section of a broken branch, and was exposed to almost direct sunlight. It was very delicate and easily damaged just by touching. (additional note added)
The branch itself, had been lying on the ground long enough for the bark (although intack), had been softened by moisture. The mycelium had not been exposed by me, and was in its total normal state as shown in the image. I have observed something similar to this but it was always under the bark in a moist light protected area.

no way to know without microscopy.

the only other things I’ve seen that looked remotely similar were Cordyceps relatives, and those are parasites on truffles and insects; this seems clearly to be saprobic on wood. That same mycelium strongly points to the wood itself being the substrate.

And those are also pyrenomycetes as I recall.

it reminds of a “corticioid” fungus, but those are crust fungi. This is not a crust. As for the visible mycelium, perhaps that’s because the branch has been debarked?

to vote against Xylaria hypoxylon is written in my first comment – in english.
I see no reason to repeat it, or to defend my point of view any further.

This fits

my field guide’s images of X. hypoxylon to a T. And also does not fit anything else.

I continue to be baffled regarding why every so often someone feels the need to pick some random identification of mine and argue against it regardless of how well it fits. And as near as I have been able to determine, only my identifications are singled out for this “honor”, never anyone else’s.

If it looks like fungus Q and someone else says it looks like fungus Q, that tends to be left alone. If it’s not left alone, it’s because someone proposes that it’s the similar-looking fungus R instead and a debate ensues about how to reliably distinguish fungus Q from fungus R.

On the other hand, if it looks like fungus Q and I say it looks like fungus Q, then very often someone will vote against Q after a short time, usually without even bothering to propose something else they think it is instead. They don’t propose a fungus R it might be instead; they just say no way it’s Q. And, oddly, it seems that in a very large fraction of these cases Irene is one of the naysayers.

If there’s an explanation for the above observation other than politically-motivated voting, I’d love to know what it is. (Except if your “explanation” would consist of personal attacks rather than something more reasonable, of course.)

I don’t want to see this site marred by some kind of pointless and petty factionalism. I have no interest in polarizing the site into, say, some group with me in it and some group with Irene in it that for some reason are at war and each group bolsters its own names and votes against the other’s. That does not strike me as a sensible way to generate IDs.

Unfortunately, it looks like perhaps not everyone agrees with me that the above is not a sensible way to generate IDs…

I have never seen anything like this, but the way it grows, with mycelium threads (rhizomorphs) on the surface of the branch, it reminds of a corticioid fungus. Maybe something in the vicinity of Kavinia or Lentaria?

Xylaria is a pyrenomycete, a genus of ascomycetes with perithecia in a black stroma, often seen with white tips, covered with conidia. Xylaria hypoxylon is often branched, the branches have a tough and woody context, are 3-5 mm broad and more than ten times higher.. There are smaller members of this genus, but this obs is not a pyrenomycete. You will never find them connected with a conspicious mycelium like this.
